BOLT-CUTTE R.

A SPECIFICATION forming par-t of Letters Patent No. 372,756, datedNovember 8, 1887.

- Application ilcd April 16, 1857. Serial No. 235,117. (No model.) f

To all whom it may concern: j

Beit known that we, GEORGE SIGEL LONNON and FRANK MALLETT, citizens ofthe United States, residing at South Pueblo, in the county of Pueblo andState of Colorado, have invented new and useful improvementsinBolt-Cu'tters,

l of which the following is a specification.

Our invention relates to improvements in bolt-cutters; and it consistsin a certain novel construction and arrangement of parts for service,fully set forth hereinafter, and specifically pointed-Out in the claim.

In the accompanying drawings, Figure l is a side view of our cutter.Fig. 2 is a face or front view thereof. Fig. 3 is a side view with thejaws open. Fig. 4 is a detail perspective view of the stop for thehandles. Fig. 5 is a similar view of the upper ends ofthe handles,showing the cani ends thereon.

Referring to the drawings, in which similar letters denote correspondingparts in all the igures, A A designate the handles or reins of thecutter pivoted together at the ripper ends by the bolt B, which alsopasses through eyes in the lower ends of the arms C C of the link C. Thesaid reins are widened toward the upper ends and extended a shortdistance above the bolt B, and the said projecting portions are roundedto form cams D D, for a purpose hereinafter explained.

E is a rigid or stationary jaw of the cutter, semicircular in forni,with the cuttingedge or knife E having a straight or vertical face, asshown, and the said jaw is firmly secured to the upper end of the saidlink, between the arms thereof, by having a perforation in the upperside of said jaw passed over a short stud on the under side of the saidupper end of the link.

F is the movable jaw, similar in shape to the upper or rigid jaw,pivotally secured at the rear end to the rear end of the said upper jawand adapted to operate vertically between the lower ends of the arms ofthe link.

G is a iiatleaf-spring bent into a curved form and placed between thesaid jaws, with the ends thereof pressing, respectively, against theunder side of the upper jaw and the upper side of the lower jaw. Thisspring forces the jaws E F apart, and the jaw F will move in the planeof the jaw E, so that when the edges ofthe knives are forced togetherthey will cut directly and effectively. It will be seen that the springG is sufficiently strong to securely and firmly hold the upper jaw inplace on the stud, before mentioned, in the upper end ofthe link, evenwhen the lower jaw is lowered to its farthest extent.

When the reins or handles are spread, as seen in Fig. 3, thejaws will beseparated by the action of the said spring, and as the said reins aredrawn toward each other the cams on the upper ends thereof,operatingagainst the lower surface of the movable jaw, will force it upand cause the edges of the knives to bite together.

H'represents an adjustable stop, comprising a body, I, having an openingtherein to receive one of the reins, the thumbscrew l', to impinge atthe inner end against the said handle and bind the said stop in thedesired po sition, and the ear or projection l2 on the side of the saidbody, adapted to serve as alimit to the motion of the handles andprevent the same from passing each other. The object of the said stop isto prevent the edges of the k nives from coming in contact with eachother;

and it will be understood that the closer thel said stop is`placed tothe fulcrum` or pivot of the handles the farther apart the lower endsthereof will be held and the lcss will be the motion of the knives.

When it is desired to lay aside the tool, the stop is removed, thehandles brought together, and the 4stop replaced, with the ear orprojection on the under side of the handles, thus holding them togetherso that they occupy less space than when extended by the action of thespring.

It is not absolutely necessary to remove the stop to lock the tool inthe closed position, as there is sufficient lateral give or spring inthe handles to allow the same to be sprung apart far enough to pass thesaid ear or projection, and thus lock the jaws and handles without theinconvenience above mentioned.

K is a small stud on the side of the lower jaw, to prevent the samefrom. being drawn accidentally out of the link, thus providing means tomaintain the parts of the tool in their proper relative position,as seenin the annexed drawings and herein described.

IOO

The operation of the implement will be readily understood from theforegoing description, and it will be seen that it is a simple, light,and strong device, well adapted in every way to satisfactorilyaccomplish the work for which it is designed. The link embracing thejaws, being placed at the front ends thereof, is adapted to serve as apowerful brace thereto, to prevent all straining of the tool. The action1o of the movablejaw is direct, guided laterally by the side arms of thelink, and is prevented from being displaced by the stud on the sidethereof. The leaf-spring is held securely in place laterally by the saidside arms, and is I 5 prevented from slipping forward by the rear sidesof the knives or cutters. The power eX- erted upon the lower side of thelower jaw by the two cams situated only a very short distance from thefulcrum, and actuated by the 2o long handles or reins on the oppositeside of the said fulcrum, is very great,the leverage being tremendousand calculated to raise the said movable jaw with force sufficient tosever any bolt which is possible to be received between the jaws; also,the device provided for limiting the motion of the jaws is extremelyeffective, and by simply removing the stop and replacing it afterpassing the handles, or byy springing the handles slightly apart, thesaid stop is caused to perform the function of a lock to the reins andjaws to prevent their spreading by the action of the spring.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is-

The combination, with the handles, of the stop H, placed on one of thehandles and secured thereto by the thumb-screw I', and provided with theprojection I2, arranged in the path of the other-handle, substantiallyas specied.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
